https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=253488 Bug ID: 253488 Summary: wg(4) IPv6 endpoints not supported yet Product: Base System Version: 13.0-STABLE Hardware: amd64 OS: Any Status: New Keywords: ipv6 Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: zarychtam@plan-b.pwste.edu.pl I have asked on D26137 review, then on the freebsd-net@ mailing list but haven't received any useful feedback on this matter, though the code suggests IPv6 endpoints are implemented. When IPv6 endpoint is specified in the form: [IP:v6::address]:port while creating the tunnel from the command line we get only the error: wg0: wg_peer_add bad length for endpoint 28 So I modified code in sys/dev/if_wg/module/module.c[1] around line 590 to skip this check but compare the lengths. It came out that after this change Wireguard protocol is able to do a handshake with IPv6 specified endpoint, but sizeof(*endpoint)[1] seems to be always 16(for both legacy IP and IPv6 specified endpoints), what is fine for legacy IP, while for IPv6 endpoint size is 28. After disabling this check no more than Wireguard handshake over IPv6 can be observed. The tunnel is either not created or not able to carry the data.[2] [1] https://cgit.freebsd.org/src/tree/sys/dev/if_wg/module/module.c?id=5aaea4b#n590 [2] https://lists.freebsd.org/pipermail/freebsd-net/2021-February/057463.html -- You are receiving this mail because: You are the assignee for the bug.home | help
